FASTENING DEVICE.

Application filed May 28,

To all whom it may concern:

Be it known that I, JAooB F. LANGENAU, a citizen of the United States,and a resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Fastening Devices, of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions.

The present improvements, relating, as indicated, to fastening devices,have more particular regard to looks or hasps of the sort used ontrunks, suit cases and the like, characterized by having a hasp in theform of a link that is carried by a pivotal member so as to engage witha hook-like member or projection when in looking position. The

object of the present invention is to provide supplemental means forsecuring such pivotal member in place when the hasp is in such lockingposition, the means ordinarily provided for this purpose consisting of apin or stud member which more or less tightly fits into an aperture inthe base plate to which said member is attached.

To the accomplishment of the foregoing and related ends, the invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims, the annexed drawing and the followingdescription illustrating but several of the various mechanical forms inwhich the principle of the invention may be embodied.

In said annexed drawing Fig. 1.is a front elevation or plan view of afastening device embodying one form of my prevent improvements, saiddevice heing shown in its closed or looking position;

Fig. 2 is a side elevation of said device with parts shown in section asindicated by the line 22, Fig. 1; and Fig. 3 is a view similar to Fig.1, but showing the pivotal hasp-carrying member removed so as todisclose more clearly the supplemental locking device.

Referring to the constructional form of the invention illustrated inFigs. 1, 2 and 3,

the familiar parts of the fastening device comprise two base plate 1 and2, which are respectively designed to be secured in abutting relation tothe main body and the cover or lid of the trunk, suit case or othersimilar article. R-igidly attached to said plate 1 1920. Serial NO.384,809.

is a hoolslike projection 8, the undercut face of which extends in adirection away from the edge of the plate lying in abutting relation toplate 2. Rigidly attached to the latter is a projection 4;, preferablyin the ber 6 is swung outwardly, to engage beneath the hook-likeprojection 3 on plate 1, and when said member 6 is thereupon pressedbackwardly against the plate 2, the two plates, with the parts of thetrunk or equivalent article, will be forcibly drawn together.

As shown, the pivotal axis 5 of the memher 6 should lie without theplane of the link in the locking position of the parts just described soas to minimize the tendency for the member 6 to swing outwardly toreleasing position; however, I have found it desirable to add asupplemental locking device in order to insure against any butpurposeful opening of the lock. With this in view the upper end 8 of themember 6, which is curved to present a convenient finger piece foroperation of the look, as

shown in Figs. 1, 2 and 3, is formed with an aperture 9 adapted to fitover a V- shaped stud 10 that projects outwardly from the face of theplate 2, or rather from a supplemental plate 11 secured there to.Slidably secured in place by means of such supplemental plate 11 is areciprocable member 12 carrying an undercut stud 13 that projectsthrough an aperture 14 in said plate 11 laterally adjacent to said stud10. A spring 15 is disposed behind the slidable member 12 so as to pressthe latter outwardly, and thus force the stud 13 into locking engagementwith the aperture 9 in the handle-extension 8, as shown in Figs. 1 and2. The outer face of the stud 13 is beveled to conform with that of thestud 10, so that said handle-extension maybe forced down over said stud13 without manipulating the slide 12; however, the outer end 16 of thelatter is upturned for convenience in pressing the slide back when it isdesired to release said extension from said stud 13.

The foregoing supplemental locking device, it will accordingly be seen,affords simple and yet effective means for p0sitively retaining themember 6 With the hasp 7 in locking position. There is of course noparticular strain placed upon the stud 13, so that the parts of suchsupplemental locking device may be made of relatively lightconstruction, and yet prove sufliciently substantial for the purpose inhand.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any or the followingclaims or the equivalent of such stated means be employed.

1 therefore particularly point out and distinctly claim as myinvention 1. In a fastening device of the character described, thecombination with two plates designed to be secured in abutting relationon the parts to be fastened together, a hooklike projection rigidlymounted on one of said plates, a member pivotally attached to the otherplate, and a link carried by said member and adapted to engage saidpr0jection to lock said plates together, said memher being formed withan aperture adjacent its free end; of a guide stud fixed on thecorresponding plate adapted to be received in the aperture in saidmember; and a slide carried by said plate and provided with an undercutstud lying alongside such firstmentloned stud and adapted in oneposition of said slide to inter-lock with said aperture.

2. In a fastening device of the character its free end; of a guide studfixed on the COI responding plate adapted to be received in the aperturein said member; a slide carried by said plate and provided with anundercut stud lying alongside such first-mentioned stud and adapted inone position of said slide to interlock with said aperture; and a springnormally holding said slide with said last-mentioned stud in suchlocking position, said slide being formed with a linger piece foroperating the same against said spring.

Signed by me, this 26th day 01 May, 1920.

JACOB F. LANGENAU.
